For questions about devices used to track the location of something; typically a device containing a GPS receiver and a cellular modem. Also for inverse tracking of objects as they move, but not for general inventory tracking.

Use this tag for questions which ask about a device which performs a tracking function (either of its own location, or of other objects which pass from one sensor location to another). Do not use this tag to ask about inventory tracking (such as a smart fridge which counts inventory by identifying them going in and out).

Questions asked here should be specific to a connected function. If there is no connected function then the question is probably more appropriate on Electrical Engineering.
